Biography
Hanzo Hattori was born in Mikawa Province to the Hattori clan, who served the Tokugawa clan. He often returned to Iga Province, the home of the Hattori clan, and he trained as a professional ninja. He taught many ninjas such as Nene, the wife of Hideyoshi Hashiba. His first battle was the Battle of Anegawa in 1570, followed by Mikatagahara in 1573.

Hanzo's most famous feat was the escape from Iga in 1582, in which he escorted his master Ieyasu Tokugawa and the Tokugawa army away from the army of Mitsuhide Akechi, who had slew Nobunaga Oda and took over Kyoto. He was able to hold back the Akechi army and prevent Tokugawa from being assassinated en route to safety, and he gained fame for appearing and disappearing, as well as other ninja skills.

He proceeded to serve under Ieyasu for the rest of his life, taking part in the Battle of Sekigahara, where he launched sneak attacks on the Western Army lines. His other great feat occurred in 1615 during the Siege of Osaka, where he snuck into the Osaka Castle Main Ward and mortally wounded Hideyori Toyotomi. He died during the siege, struck down by the hard-fighting defenders.
